i am trying to start a c++ exe file from c# by a click of a button , but it is throwing an Exception of type 'System.Exception' at process.start(); , although the file is correct . i have tried :

    private void button2_Click(object sender, EventArgs e)
    {        
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.FileName = "E:\\tc\\5a.exe";
            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.Start();
    }

when i view details of this exception it shows "The parameter is incorrect" the file is present at e:\tc

when i do same thing but in filename i keep "cmd.exe" it works . thank you in advance
